OVERVIEW & CHEVY SMALL BLOCK V8 KIT

SysteMAXTM ENGINE KITS - AN OVERVIEW

SysteMAX engine packages are systems designed to take the guesswork out of choosing the correct combination of components that will best MAXimize the performance of a small block/big block Chevrolet engine or a small block Ford engine. They are total air flow management systems composed of matched components that, working in unison will enable you to achieve a level of performance and power that you always dreamed about.

The following are available:

SysteMAX P/N

300-501-1 300-502 300-503-1

Engine Application

Ford 5.0 L (EFI) Chevrolet 350 (carbureted) Chevrolet 350 (carbureted)

Horsepower

350 @ 5750 RPM 350 @ 4500 RPM 425 @ 6100 RPM

The Ford 5.0 L EFI systems are designed specifically for the 198693 EFI engines. All kits are available either carbureted or fuel injected.

SysteMAX kits feature top quality Holley, Lunati and Weiand brand components such as cylinder heads, intake manifold, timing chain and gear set and camshaft and lifters. Carburetors are not included, but a Holley carburetor recommendation is made that's based on dynamometer testing results.

SysteMAX is designed to be delivered as a complete kit because it ideally matches the components for maximum performance. For those on a budget, however, Holley offers SysteMAX on a component basis.

The Holley SysteMAX line will continue to be expanded with additional engine applications and different component combinations such as blower kits. The Holley SysteMAX line allows multiple choices in how you can set up an engine and will keep you on top of the horsepower race!

CHEVROLET SMALL BLOCK V8 - (1962-86) Part # 300-502 (B)

Comments/ Recommendations A potent, but very driveable street package for a basic stock motor. Add Hooker or FlowTech headers and a 750 CFM vacuum secondary Holley carburetor to tie this package together.

SysteMAX Recommendations

It's recommended that a 4-bolt main short block be used, although a good 2-bolt main short block can also be used. Minimum cylinder head valve size requirement is 1.94" intake diameter and 1.50" exhaust diameter. Compression requirement is 9.8:1. Holley testing was conducted with a 750 CFM vacuum secondary carburetor, P/N 0-3310. A good set of 1-5/8" tube headers used in conjunction with some high-flow/low back pressure mufflers won't hurt you either. If you're running an automatic transmission a 2,000-2,500 RPM stall converter will help lower drag strip times. New, top quality gaskets for your specific application are required separately and are not part of the package.

CHEVROLET 302, 327, 350 V8 - (1968-86) Part # 300-503-1 (B)

Comments/Recommendations

This is a maximum performance carbureted street kit that will really light your fire! A zero-decked

block with 4-bolt mains and a forged steel crankshaft will get you started. Add Lunati Street Race rods,

P/N LHA1; Lunati flat top pistons, P/N 13H1J2S0 for standard bore engines and P/N 13H1J2S3 for

+.030" over engines (to achieve 10:1 compression ratio) and Lunati roller rocker arms, P/N 84146 and

you end up with a reliable combination of components that will perform. Top it all off with a set of

Hooker or FlowTech headers and a 750 CFM Holley and you'll have what it takes. NOS nitrous,

of course, is optional.

Holley testing used a 750 CFM double pump carburetor, P/N 0-4779S with a set of 1-3/4" Hooker Super Comp tube headers and high-flow, low-back-pressure mufflers. When using a TH-350 then a 3,000+ RPM stall converter will help lower drag strip times. When using a TH-700R4 transmission, a 2,500+ RPM stall converter will perform best. For allaround great street/strip performance a rear axle ratio of around 3.55 should be used. A set of Lunati, P/N 84146, roller rocker arms is also recommended. New, top quality gaskets for your specific application are required separately and are not part of the package.

FORD 5.0L H.O. EFI ENGINE (1986-93) Part # 300-501-1 (B)

Comments/Recommendations

A maximum performance, but very streetable package for the Ford 5.0L H.O. EFI V8. This one will really

let your Mustang kick up its heels! Additional parts recommendations: Holley 70mm Ford throttle body,

P/N 112-500; 24 or 30 lb./hr. Holley fuel injectors; Holley 70mm EGR spacer, P/N 112-550; 70mm

mass air flow meter; Holley 190 liters per hour in-tank electric fuel pump, P/N 12-901; Holley adjustable

fuel pressure regulator, P/N 512-500-1; Lunati 1.6:1 roller rockers, P/N 84160. Add a set of 1-5/8" tube

headers (Hooker P/N 6128 or FlowTech P/N 12110), "cat-back" system (Hooker P/N 16862 or FlowTech

P/N 42604) and Hooker Aero Chamber mufflers, P/N 21502. Note: FlowTech's cat-back system contains

mufflers but requires an H-pipe, P/N 53605.
